I prefer the xbox controller, concave triggers and sticks so you're fingers have better control and grip, the sticks have little dots that help you feel your way to dead front (usefull in bowling or golf games where precision is key) and the overall shape fits in your hands better.
But the Ps3 buttons are a better shape and push down better, especially the D-pad. But liked mentioned above the original controller was good, the sticks just tacked on. Funnily enough I find the six axis more accurate at measureing my movement than the wiimote does.
But when you get used to either controller you don't notice any of the problems, they work 100%
